Замечания
Within the Microsoft Visual Studio Tools for Applications (VSTA) scripting environment, the Script task provides the global Dts object, which gives the developer programmatic access to objects defined elsewhere in the package, such as connections, variables, and events, through the properties and methods of the ScriptObjectModel class. The Dts object is an instance of the ScriptObjectModel class.
Примеры
The following sample of code for use inside a Script task demonstrates the use of the Variables, Events, and TaskResult properties. For more information, see Запрос Active Directory в задаче «Скрипт».
Public Sub Main()
Dim directory As DirectoryServices.DirectorySearcher
Dim result As DirectoryServices.SearchResult
Dim email As String
email = Dts.Variables("email").Value.ToString
Try
directory = New _
DirectoryServices.DirectorySearcher("(mail=" & email & ")")
result = directory.FindOne
Dts.Variables("name").Value = _
result.Properties("displayname").ToString
Dts.Variables("title").Value = _
result.Properties("title").ToString
Dts.TaskResult = ScriptResults.Success
Catch ex As Exception
Dts.Events.FireError(0, _
"Script Task Example", _
ex.Message & ControlChars.CrLf & ex.StackTrace, _
String.Empty, 0)
Dts.TaskResult = ScriptResults.Failure
End Try
End Sub
